\title{Boolean types}
\format{
An object of class \code{ordered} (inherits from \code{factor}) of length 6.
}
\usage{
booltypes
}
\description{
The \code{\link{ordered}} factor \code{booltypes} ranks the boolean types.
}
\details{
There are currently six boolean types, \code{booltypes} is an \code{\link{ordered}} vector with the following ordinal \code{\link{levels}} \describe{
\item{nobool}{non-boolean types}
\item{\code{\link{logical}}}{for representing any boolean data including \code{NA} }
\item{\code{\link{bit}}}{for representing dense boolean data }
\item{\code{\link{bitwhich}}}{for representing sparse (skewed) boolean data }
\item{\code{\link{which}}}{for representing sparse boolean data with few \code{TRUE}}
\item{\code{\link{ri}}}{range-indexing, for representing sparse boolean data with a single range of \code{TRUE} }
}
\code{booltypes} has a \code{\link{names}} attribute such that elements can be selected by name.
}
\note{
do not rely on the internal integer codes of these levels, we might add-in \code{\link[ff]{hi}} later
}
